Start Bay is the bay in the English Channel in Devon, England between the River Dart's estuary and Start Point. On the coast, from south to north, are Hallsands, Beesands, Torcross, the Slapton Sands, Strete, Blackpool Sands and Stoke Fleming. The South West Coast Path covers much of the coastline.
The 4-gun Royal Navy cutter Friendship was stationed in Start Bay as a patrol vessel between 1763 and 1771.
The United States Army used Slapton Sands in Start Bay to rehearse the Normandy landings in 1944.
